## What is the torque of a DC motor?

The sum of the torques due to all armature conductors is known as gross or armature torque (Ta). Now i = Ia/A, B = φ/a where a is the x-sectional area of flux path per pole at radius r. Clearly, a = 2πrl/P. Hence torque in a d.c. motor is directly proportional to flux per pole and armature current.

## What are the 3 types of DC motors?

There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.

## What determines torque in a DC motor?

Torque of a motor is directly proportional to current. Therefore, the maximum torque a motor can produce is limited by the maximum current it can handle.

## In which type of DC motor starting torque is maximum?

Series wound DC motors are best for applications that require high startup torque, without the need for speed regulation. Like a shunt motor, as a load is applied to a DC series motor, the motor speed decreases, which reduces the back EMF and increases the net voltage.

## What is motor torque formula?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

## What are the 4 types of DC motor?

There are 4 main types of DC motors:

• Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
• Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
• Shunt DC Motors. …
• Compound DC Motors.

## What is shunt in DC motor?

A shunt motor is a direct current motor whose two windings are in parallel, with the same voltage across each. … A shunt motor is designed to run at practically constant speed, regardless of the load. A shunt motor is a direct current motor whose two windings are in parallel, with the same voltage across each.

## What is different types of motors?

The types of Electric motors are available in three main segments like AC motor, DC motor, & special purpose motors.
